Dell will not be interested unless the adapter is running the most
recent firmware.

Dell, (maybe) Scott and I recomend that you ensure you're on the
latest firmware:

[firewall2] ~ # mfiutil -u0 show adapter
mfi0 Adapter:
    Product Name: PERC 6/i Adapter
   Serial Number: 1122334455667788
        Firmware: 6.2.0-0013
     RAID Levels: JBOD, RAID0, RAID1, RAID5, RAID6, RAID10, RAID50
  Battery Backup: present
           NVRAM: 32K
  Onboard Memory: 256M
  Minimum Stripe: 8K
  Maximum Stripe: 1M

I'm sure there are bugs on this firmware too, but reading the fixes
that were made between the version that came on the adapter and
this version were Truely Frightening.

It's trivial to update the firmware with the mfiutl program.
